Fizz Keeper
A Fizz-Keeper is a type of Closure (container), closure that is marketed as a way to keep carbonation in soft drinks. It consists of a small round hand pump that is screwed onto the top of a plastic soft drink bottle, which is then used to pump air into the bottle, preventing the drink from going flat. Research into the Fizz-Keeper's mechanisms and processes has shown that the Fizz-Keeper, let alone pressurizing a soda bottle, does not actually prevent loss of carbonation, with its marketed claims being dismissed as pseudoscience. Description The first Fizz-Keeper-like device was patented in 1926 by G. Staunton. T.R. Robinson and M.B. Beyer patented the Fizz-Keeper itself in 1988, without claiming in the patent that the device maintained a soft drink's carbonation. Several styles of device exist, from the plain piston pump to devices incorporating a bulb and a latch and hinge device to allow liquid to be poured out of a spout without removing the Fizz-Keeper from the bottle.

Closure (container)
A closure is a device used to close or seal a container such as a bottle, jug, jar, tube, or can. A closure may be a cap, cover, lid, plug, liner, or the like. The part of the container to which the closure is applied is called the finish. Other types of containers such as boxes and drums may also have closures but are not discussed in this article. Many containers and packages require a means of closing, which can be a separate device or seal or sometimes an integral latch or lock. Purpose of closures The closure is often the most critical part of a package, and must fulfill all of the basic functions of packaging in addition to being easy to open and (if applicable) reclose. Depending on the contents and container, closures have several functions: * Keep the container closed and the contents contained for the specified shelf life until time of opening * Provide a barrier to dirt, oxygen, moisture, etc. Control of permeation is critical to many types of products: foods, ...

Carbonation
Carbonation is the chemical reaction of carbon dioxide to give carbonates, bicarbonates, and carbonic acid. In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids. In inorganic chemistry and geology, carbonation is common. Metal hydroxides (MOH) and metal oxides (M'O) react with CO2 to give bicarbonates and carbonates: :MOH + CO2 → M(HCO3) :M'O + CO2 → M'CO3 In reinforced concrete, the chemical reaction between carbon dioxide in the air and calcium hydroxide and hydrated calcium silicate in the concrete is known as neutralisation. The similar reaction in which calcium hydroxide from cement reacts with carbon dioxide and forms insoluble calcium carbonate is carbonatation. Henry's law Henry's law states that P=KBx where P is the partial pressure of gas above the solution. KB is Henry's law constant. KB increases as temperature increases. x is the mole fraction In chemistry, the mole fraction or mol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soft Drink
A soft drink (see § Terminology for other names) is a drink that usually contains water (often carbonated), a sweetener, and a natural and/or artificial flavoring. The sweetener may be a sugar, high-fructose corn syrup, fruit juice, a sugar substitute (in the case of ''diet drinks''), or some combination of these. Soft drinks may also contain caffeine, colorings, preservatives, and/or other ingredients. Soft drinks are called "soft" in contrast with "hard" alcoholic drinks. Small amounts of alcohol may be present in a soft drink, but the alcohol content must be less than 0.5% of the total volume of the drink in many countries and localities See §7.71, paragraphs (e) and (f). if the drink is to be considered non-alcoholic. Types of soft drinks include lemon-lime drinks, orange soda, cola, grape soda, ginger ale, and root beer. Soft drinks may be served cold, over ice cubes, or at room temperature. They are available in many container formats, including cans, glass bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Pump
Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another. They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities. There are many different types of hand pump available, mainly operating on a piston, diaphragm or rotary vane principle with a check valve on the entry and exit ports to the chamber operating in opposing directions. Most hand pumps are either piston pumps or plunger pumps, and are positive displacement. Hand pumps are commonly used in developing countries for both community supply and self-supply of water and can be installed on boreholes or hand-dug wells. History One sort of pump once common worldwide was a hand-powered water pump, or 'pitcher pump'. It was commonly installed over community water wells in the days before piped water supplies. In parts of Britain and Ireland, it was often called ''the parish pump' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudoscience
Pseudoscience consists of statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method. Pseudoscience is often characterized by contradictory, exaggerated or falsifiability, unfalsifiable claims; reliance on confirmation bias rather than rigorous attempts at refutation; lack of openness to Peer review, evaluation by other experts; absence of systematic practices when developing Hypothesis, hypotheses; and continued adherence long after the pseudoscientific hypotheses have been experimentally discredited. The demarcation problem, demarcation between science and pseudoscience has scientific, philosophical, and political implications. Philosophers debate the nature of science and the general criteria for drawing the line between scientific theory, scientific theories and pseudoscientific beliefs, but there is general agreement on examples such as ancient astronauts, climate change denial, dowsing, evolution denial, ...

Dalton's Law
Dalton's law (also called Dalton's law of partial pressures) states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases. This empirical law was observed by John Dalton in 1801 and published in 1802.J. Dalton (1802)"Essay IV. On the expansion of elastic fluids by heat,"''Memoirs of the Literary and Philosophical Society of Manchester'', vol. 5, pt. 2, pages 595–602; see page 600. Dalton's law is related to the ideal gas laws. Formula Mathematically, the pressure of a mixture of non-reactive gases can be defined as the summation: p_\text = \sum_^n p_i = p_1+p_2+p_3+\cdots+p_n where ''p''1, ''p''2, ..., ''pn'' represent the partial pressures of each component. p_ = p_\text x_i where ''xi'' is the mole fraction of the ''i''th component in the total mixture of ''n'' components . Volume-based concentration The relationship below provides a way to determine the volume-based concentration of any ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ideal Gas
An ideal gas is a theoretical gas composed of many randomly moving point particles that are not subject to interparticle interactions. The ideal gas concept is useful because it obeys the ideal gas law, a simplified equation of state, and is amenable to analysis under statistical mechanics. The requirement of zero interaction can often be relaxed if, for example, the interaction is perfectly elastic or regarded as point-like collisions. Under various conditions of temperature and pressure, many real gases behave qualitatively like an ideal gas where the gas molecules (or atoms for monatomic gas) play the role of the ideal particles. Many gases such as nitrogen, oxygen, hydrogen, noble gases, some heavier gases like carbon dioxide and mixtures such as air, can be treated as ideal gases within reasonable tolerances over a considerable parameter range around standard temperature and pressure. Generally, a gas behaves more like an ideal gas at higher temperature and lower pressu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry's Law
In physical chemistry, Henry's law is a gas law that states that the amount of dissolved gas in a liquid is directly proportional to its partial pressure above the liquid. The proportionality factor is called Henry's law constant. It was formulated by the English chemist William Henry, who studied the topic in the early 19th century. An example where Henry's law is at play is in the depth-dependent dissolution of oxygen and nitrogen in the blood of underwater divers that changes during decompression, leading to decompression sickness. An everyday example is given by one's experience with carbonated soft drinks, which contain dissolved carbon dioxide. Before opening, the gas above the drink in its container is almost pure carbon dioxide, at a pressure higher than atmospheric pressure. After the bottle is opened, this gas escapes, moving the partial pressure of carbon dioxide above the liquid to be much lower, resulting in degassing as the dissolved carbon dioxide comes out of the ...

Bottles
A bottle is a narrow-necked container made of an impermeable material (such as glass, plastic or aluminium) in various shapes and sizes that stores and transports liquids. Its mouth, at the bottling line, can be sealed with an internal stopper, an external bottle cap, a closure, or induction sealing. Etymology First attested in 14th century. From the English word ''bottle'' derives from an Old French word ''boteille'', from vulgar Latin ''butticula'', from late Latin ''buttis'' ("cask"), a latinisation of the Greek βοῦττις (''bouttis'') ("vessel"). Types Glass Wine The glass bottle represented an important development in the history of wine, because, when combined with a high-quality stopper such as a cork, it allowed long-term aging of wine. Glass has all the qualities required for long-term storage. It eventually gave rise to "château bottling", the practice where an estate's wine is put in a bottle at the source, rather than by a merchant. Prior to this, w ...
